Hi All, I was able to take the timestamp from the cartridge agent (WSO2CEPHealthStatisticsPublisher and WSO2CEPInFlightRequestPublisher) to CEP PayLoad definition.Git Hub commits can be found here[1], [2]. Currently working on sending the timestamp to the RDBMS without conflicting execution plans.
I have included the read-me [2] file to the cep extensions how to configure should happen for the Health Stat publishing to the RDBMS.
